Spectral and Magnetic Properties of $\alpha$- and $\gamma$-Ce from Dynamical Mean-Field Theory and Local Density Approximation

We present excitation spectra for Ce metal obtained with an ab initio scheme combining local density approximation and dynamical mean-field theory including itinerant $\mathrm{spd}$ and correlated $f$ states. The local interactions among the $f$ electrons lead to typical many-body resonances in the $f$ density of states (DOS), such as lower and upper Hubbard bands and the Kondo resonance. The $\mathrm{spd}$ DOS show weak renormalization effects due to hybridization. We observe different Kondo temperatures for $\alpha$- and $\gamma$-Ce due to strong volume dependence of the effective hybridization strength for the localized $f$ electrons. Finally we compare our results with a variety of experimental data.
